Hi, No it is not possible.
The PowerVault MD32xx enclosure can be cascaded to as many as seven MD12xx expansion enclosures. The enclosures must be "cold-add." The MD32xx and all MD12xx expansion enclosures must be powered down for expansion cabling.
Cascading enclosures that have preexisting data on them can potentially be a data-destructive operation. The metadata format (DACstore) of configured drives in the MD32xx may differ from the Disk Data Format used on configured drives in the MD12xx enclosure, especially if the enclosure was previously attached to a PowerEdge RAID Controller or other dissimilar controller. Backups should be completed prior to any configuration changes to protect the integrity of the data.
Enclosure Power-Up Sequence
The following procedure should be followed for the power-up sequence of an MD32xx with attached MD12xx expansion enclosures.
Turn on the MD12xx expansion enclosure(s). Wait for the expansion status LED to light blue on each enclosure.
Turn on the MD32xx and wait for the status LED to indicate that the unit is ready:
If the status LEDs light a solid amber, the MD32xx is still coming online.
If the status LEDs are blinking amber, there is an error that can be viewed using MDSM.
If the status LEDs light a solid blue, the MD32xx is ready.
After the MD32xx is online and ready, turn on any attached host systems.
The power-down sequence should done in the reverse order, with emphasis on a clean shutdown of the hosts and at least a ten second interval thereafter to insure that controller cache has been completely flushed
